Generally, no — a tenant in Ontario should not unilaterally withhold or reduce rent because a landlord has failed to make repairs, even where the landlord is clearly in breach of their maintenance obligations under the Residential Tenancies Act. Withholding rent can expose the tenant to an N4 notice and an eviction application for non-payment. The correct remedy is to keep paying full rent and file a T6 application with the Landlord and Tenant Board, which can order repairs, a rent abatement (a partial refund for the period of inadequate service), and compensation for related costs.
- Tenants should not unilaterally withhold rent over repair problems, even where the landlord is clearly at fault.
- Withholding rent risks an N4 notice and an eviction application for non-payment, regardless of how justified the underlying complaint is.
- The correct remedy is a T6 application to the Landlord and Tenant Board — keep paying rent and let the LTB order the right remedy.
- A successful T6 can result in a rent abatement — a partial or full refund for the period the unit was inadequately maintained — plus other compensation.
- A landlord generally cannot evict a tenant in retaliation for filing a T6 application or otherwise asserting their maintenance rights.
- Documentation — photos, dated messages to the landlord, repair records — is what actually determines how strong a T6 application is.
The Short Answer
No — a tenant generally should not simply withhold or reduce rent because a landlord has failed to make repairs, even where the landlord is plainly in breach of their legal maintenance duty. The risk is real: an N4 notice and an eviction application for non-payment can follow, regardless of how justified the underlying complaint is. The right path is a T6 application to the Landlord and Tenant Board, while continuing to pay rent in full.
Why Withholding Rent Is Risky
Ontario's system does not treat unpaid repairs as an automatic defence to non-payment of rent. If a tenant stops paying, the landlord can serve an N4 notice and apply to the LTB for an eviction order based on the arrears — and the repair issue, while relevant, does not automatically prevent that process from moving forward. A tenant who withholds rent is effectively trading a maintenance problem for a much more serious risk: the tenancy itself.
Some tenants assume they can simply pay for the repair themselves and deduct the cost from rent. In Ontario, this generally requires a specific Board order authorizing it — it is not something a tenant can decide unilaterally, no matter how reasonable the repair cost seems.
The Landlord's Maintenance Duty
Under the Residential Tenancies Act, landlords must keep rental units and residential complexes in a good state of repair, complying with health, safety, housing, and maintenance standards. Our guide on landlord repair obligations and the T6 application covers this duty itself in more depth — this article focuses specifically on why withholding rent is the wrong response even when that duty is clearly breached.
The T6 Process: What You Can Actually Get
A T6 application lets the Board address the actual problem directly. Potential remedies include an order requiring the landlord to complete the repairs, a rent abatement — a partial or full refund reflecting the period the unit was inadequately maintained — compensation for any property damage the issue caused, and in appropriate cases, authorization for the tenant to arrange repairs and deduct the cost, under the Board's specific direction rather than the tenant's own initiative.
Rent abatement amounts are decided case by case based on the severity and duration of the problem — there is no fixed percentage set by law. A serious, prolonged issue like no heat in winter is generally treated very differently than a minor, short-lived inconvenience.
What Evidence Matters
- Dated photos or video of the problem, ideally showing it over time.
- Written requests to the landlord and any response — or documented lack of response.
- Repair or inspection records, including any Property Standards complaints made to the municipality.
- Receipts for related out-of-pocket costs, such as a space heater during a heating failure.
See our general guide on preparing for an LTB hearing in Ontario for how to organize this evidence effectively before your hearing date.
Protection Against Retaliation
A landlord generally cannot use a T6 application as a reason to evict a tenant. If an adjudicator believes an eviction application is actually a response to the tenant asserting their maintenance rights, the law directs that the eviction be refused on that basis. This protection is part of why pursuing a T6 is the safer path — it is specifically designed not to put your tenancy at risk the way withholding rent can.
What to Do Instead of Withholding
Keep paying rent in full and on time, document the problem thoroughly, and file a T6 application rather than taking matters into your own hands. If you have already withheld rent and received an N4 notice, get advice immediately — see our guide on the LTB eviction timeline in Ontario for what happens next, and act quickly. Before filing, see our guide on LTB application fees. If the repair issue is connected to a pet-related dispute, pet clauses in Ontario leases may also be relevant, and if your tenant insurance or roommate situation is part of the picture, see our guides on tenant insurance requirements and roommates and joint tenancy.

Frequently Asked Questions
This is generally not a safe approach in Ontario. Withholding rent, even for a legitimate repair complaint, can expose you to an N4 notice and an eviction application for non-payment — the Landlord and Tenant Board does not treat unpaid repairs as an automatic excuse to withhold rent on your own initiative.
Continue paying full rent on time, document the problem thoroughly, and file a T6 application (Tenant Application About Maintenance) with the Landlord and Tenant Board. This lets the Board order the correct remedy — including a rent abatement — without putting your own tenancy at risk.
A rent abatement is a partial or full refund of rent already paid, awarded by the Board to compensate for a period when the unit was not properly maintained. The amount depends on the severity and duration of the problem and is decided case by case, not by a fixed formula.
The Board can order the landlord to actually complete the repairs, award compensation for damaged property caused by the maintenance issue, and in some cases authorize the tenant to arrange the repair themselves and deduct the cost from future rent — but only under a specific Board order, not as a self-help remedy.
Generally no. The law is specifically designed to prevent a landlord from evicting a tenant in retaliation for asserting their maintenance rights, and an adjudicator who believes an eviction application is retaliatory for this reason can refuse to grant it.
Dated photos or video of the problem, copies of written requests to the landlord and their responses (or lack of response), any relevant repair or inspection records, and documentation of your own out-of-pocket costs caused by the issue.
Timelines vary with current Board workload and the complexity of the issue. Serious, ongoing problems — such as no heat in winter — are generally treated with more urgency than minor, isolated issues.
